Hi Geoffrey, as the Directions API is our commercial offering I would avoid the mailing list :) (just guessing that this is spam probably for many list members)
And ask you to use the issue tracker for the API <https://github.com/graphhopper/directions-api> instead or contact us directly for further discussion. We offer free accounts up to 500 credits per day which would allow you <https://github.com/graphhopper/directions-api/blob/master/FAQ.md#what-is-one-credit> one matrix with even only 30 locations per day. Of course for your example we will offer you something more, just sign up <https://graphhopper.com/#directions-api> and let us discuss as we've already done similar with ffwdmejs.org <http://ffwdmejs.org/>, osm.org, Gnome Maps, .... > because that would mean including 6GB of world map data it is more even for the car-only profile and without CH > I do expect users to copy-paste the optaplanner-webexamples, Yes, sure. You can use your optaplanner example key and ask people to get their own Kind Regards, Peter On 26.03.2015 12:39, Geoffrey De Smet wrote: > Hi Peter at all, > > I am planning to also use graphhopper's matrix API in > optaplanner-webexamples, > to generate the distance matrix for a number of locations in a VRP. > > But I worry about my example flooding your server (which would make me > a bad citizen). > If I put no restrictions in it, and a user gives me a list n > locations, I am effectively asking for n² route distances.... > > For this reason, Google Maps has quota's in place, but those were > really annoying when I generated the data for this post: > > http://www.optaplanner.org/blog/2015/03/20/3BugsInTheUltimateAmericanRoadTrip.html > because I needed 50 locations, which is almost 2500 routes and they > only allow 2500 routes per day > (so I had one shot per day to get it right). > > Does GraphHopper have quota's in place? > If not, on what maximum number of locations should I restrict? > Note: I don't want to host my own GraphHopper server as part of > optaplanner-webexamples (because that would mean including 6GB of > world map data), so I 'd like to reach out to your service. > I do expect users to copy-paste the optaplanner-webexamples, but I 'll > put in a clear warning that they also shouldn't flood your server (=> > host their own server etc). > Wdyt? > > With kind regards, > Geoffrey De Smet > OptaPlanner lead > > > _______________________________________________ > GraphHopper mailing list > [email protected] > https://lists.openstreetmap.org/listinfo/graphhopper
